The last ten years have seen a marked increase in the use of supercritical fluids in analytical chemistry, mainly as mobile phases in chromatography. More recently, there has been a trend towards the application of these unusual fluids for the purpose of extraction and sample preparation. The combination of properties exhibited by supercritical fluids makes them uniquely suitable for this purpose. The automation of sample preparation using supercritical fluids will add a new dimension to existing chromatographic techniques: in addition to the time savings achieved by on-line sample preparation, there are the added benefits of improved reproduciblity and sensitivity. These developments will lead to the routine use of supercritical fluid extraction in analytical chemistry, which is the essence of this-book.Following a discussion of the use of supercritical fluid extraction as an off-line technique in analytical chemistry, authors concentrate on the highly important aspects of on-line sample preparation coupled to chromatography. Individual chapters, written by authorities in their fields, contain the maximum of practical advice in addition to covering appropriate theoretical detail. All relevant literature is reviewed in each chapter, providing a basic work of reference and a practical handbook in one volume.The book is directed at analytical chemists, pharmaceutical chemists and materials scientists in the industrial and academic sectors. It will also provide much useful information for instrument manufacturers.

Product Description: Explores both the benefits and limitations of new UHPLCtechnologyHigh performance liquid chromatography (HPLC) has been widelyused in analytical chemistry and biochemistry to separate,identify, and quantify compounds for decades. The science of liquidchromatography, however, was revolutionized a few years ago withthe advent of ultra-high performance liquid chromatography (UHPLC),which made it possible for researchers to analyze sample compoundswith greater speed, resolution, and sensitivity...read more

For "baby" analysis with single variable only. Appropriate for one term courses in analysis and advanced calculus. Text starts with a little logic and how to construct a proof. Revision features: material on the topology of the reals has been expanded and divided into two sections. Two optional sections on metric spaces and continuity in metric spaces have been added.

Product Description: While working as a chromatographer in the pharmaceutical industry, it became apparent to the editor that there was a pressing need for a comprehensive reference text for analysts working on the resolution of enantiomers by liquid chromatography (LC)...read more

Coverage includes an encyclopedic compendium of common substances that require trace and ultratrace analysis, and features clear discussion of such important topics as considerations for HPLC equipment, sensitive detectors, sample preparation, method development, selectivity and computer-based optimizations, optimizing detectability, and much more. 1991 (0 471-51419-5) 432 pp. High Performance Liquid Chromatography in Biotechnology Edited by William S. Hancock Analytical chemists, biochemists, and chemical engineers will find this up-to-date guide to HPLC's recent developments essential for enhancing on-the-job technical expertise. Extensive coverage includes the broad applications of HPLC, ranging from major chromatographic techniques (including reversed phase, ion exchange, affinity and hydrophobic interaction chromatography) to specific separations such as those in monoclonal antibody and nucleic acid purification. Techniques for quality control programs and advanced technology are also discussed. 1990 (0 471-82584-0) 564 pp. Unified Separation Science J. Calvin Giddings This advanced text/monograph brings together for the first time the variety of techniques used for chemical separations by outlining their common underlying mechanisms. The mass transport phenomena underlying all separation processes are developed in a simple physical-mathematical form, facilitating analysis of alternative separation techniques and the factors integral to separation power. The first six chapters provide background material applicable to a wide range of separation methods, while the final five chapters illustrate specific techniques and methods. 1991 (0 471-52089-6) 320 pp.
